[U-Boot] [PATCH] km/arm: set SPI NOR Flash default parameters
These parameters are used by the the sf probe command that are used by our update script and they therefore need to be set for all of our boards.
The timing is the same as for the ENV SPI NOR Flash (since it's the same physical device) and takes the boco2 delay on the bus into account.

No typo mistake. It's the name of a chip developped at Keymile that is the the SPI bus as well.
